I got my truck stuck up in the air when my Hi Lift Extreme jack locked up this weekend. It goes up but will not lower, I had to use a 20 year old Jack All to get the truck out of the hole I was in. The 4 month old jack is toast, outperformed by the rusty old jack all that came from a flea market lol. Anyone else had issues with the newer Hi Lift jacks?

It's virtually impossible for the jack to "crap out" or be toast. My guess is since you live in Canada that its just seized up from road grime/dirt/salt/rust. Spray the mechanism with some WD40 or other lubricant and try again.

If by some chance the pins or springs are damaged, you can by a fix it kit for like $12 that replaces those parts making it like new again.

THIS!!! Even is sunny socal I have to do this when I use my jack. When dirt gets in the pins they get a little stuck. Just spray with WD-40 before use and wiggle the pins before you jack your truck.

Yep, the climing pins are probably just dirty and the little spring isnt enough to push it back when trying to go down. Clean the jack up and lube the pins and you should be good to go. Or they do sell repair parts if necessary!

Well I wouldn't think so, I keep the jack clean enough to eat off of and it stays safe and pre-lubed inside my 4runner. I've used it with no problems buried in mud over the summer. It gets cleaned and lubed after every trip and has very little visible rust after months of use. It still only works in the up direction after cleaning it off with a power washer and spraying half a can of wd-40 on it. Wasn't impressed with that. I messed with it for some time and now I'll have to take it apart to see if I can find anything damaged. At least it happened close to home and not out in the mountains somewhere, I'd still be out there lol. Now I have to buy and carry a second jack because I don't trust this one...

Post a pic of the lifting mechanism. Let us see the pins and springs. I'm sure we can help you find the problem. Also, if its that new you should be able to return it and have it replaced under warranty, if there is truly a defect.

I had a similar problem when mine was new the spring loaded pin would stick which did not allow it to reverse but simply using a flat head screw driver to flick the "t" of the pin would release it instantly. Try taking it apart and hit the inside of the hole that spring loaded pin goes through with a light file and it will not happen anymore.

I haven't been home to mess with it. I figured that because its new, the pins are too tight and bind easily (not broken in). The smallest fragment of dirt locks up that pin no matter how many gallons of lube you spray on there. I've never had binding problems with old rusty jacks unless they were absolutely dry. I'll take a look when I'm off next week and see if I can find the issue.

This is your issue. After lubing, you need to work the jack up and down a bunch with a moderate load that you can easily remove if it binds. One way is to have a friend step on it with one foot and hold the beam while you work the handle. Do this a bunch, then go to something heavy and do that a bunch.
